Multi-tasking

It is somewhat ironic that I would praise Apple for the multi-tasking capabilities built into OS X, given that the Mac OS trailed Windows in its support for preemptive multi-tasking. Needless to say, the mistakes of yesterday are not true of OS X today, and its multi-tasking prowess was my biggest draw to it.

Multi-tasking under OS X works just like it would under Windows; you have multiple applications open, some of them doing things concurrently, while others are waiting for your input. I will address the two types of applications in a multi-tasking scenario separately.

In the case of applications running at the same time while performing tasks concurrently, OS X does one thing very well that Windows does not - the foreground application is never intruded upon by any other application that's running. Say you're encoding a video and typing a document in Word, should a dialog box popup in the encoding application, it will do it without shifting the window focus to that application. Instead, the dialog box will pop up in the background and you're free to dismiss it when you're ready and willing. It is all too often that Windows left me annoyed by a dialog box taking focus while I was typing a message to someone online or writing a document.

OS X has been designed to be as unintrusive to the user as possible. For that reason, one of the basics of the Windows interface is not echoed in OS X. While double-clicking a file or folder will open the item, hitting "enter" when one is highlighted will not cause the same effect. Instead, if you hit "enter" on a highlighted item, you'll be able to rename the item. In order to launch the file or open the folder via keyboard, you have to hit Command-Down Arrow (Command-Up Arrow will traverse up a folder tree). This takes a bit of getting used to and if approached with an open mind, you can get used to it in a couple of days, but it can be frustrating at first - especially if you are a keyboard addict used to Windows.

Another way in which OS X allows for less intrusive multi-tasking is in its ability to let you close a background window of an application other than the one you're currently working in without shifting focus to that application. Say that I have a browser window open behind a Word document that I'm typing. I can hover over the red close button on the browser window and click it without actually shifting focus away from the Word document - I can continue typing away right after clicking the browser's close button without any additional mouse use.

Next, there is the more frequently used type of multi-tasking, where multiple applications are open and the user switches between them. I've already mentioned that OS X has the equivalent of the Windows ALT-TAB functionality; the task switcher is activated by holding down the Command key and hitting "tab" to sequence through all of the open applications. Releasing Command activates the selected application and everything continues as it would under Windows.



Command-Tab in action. The more applications that you have open, the smaller each icon becomes as the Command-Tab list grows in size.


There is also the equivalent of the taskbar, which in OS X is best likened to the "dock". The dock is a fully customizable bar at the bottom of the OS X desktop (you can position the dock along any side of the screen that you'd like) and it contains application launch icons for applications to which you want quick and easy access, as well as icons of any running applications. If a running application already has its icon in the dock, a little arrow appears under the icon to denote that it's running; if not, the application's launch icon will appear to the right of the dock. The dock does have a divider to which you can also drag folders and links; to the right of this divider is where minimized windows go (with a very nice accompanying animation). Clicking on any application's icon in the dock will either launch the application if it's not already running or it will switch to that application; but, of course, that requires using that pesky mouse.

    it doesn't matter for him. but please FinalWhoever don't misinform people that need fair information to make their choice ! specially when it come to audio video pro

    some young people will make a living from it. and they'll make a better living if they choose Mac since the beginning to work.
    it's IMPORTANT !

    Regarding post #172 by Digstra, RIGHT ON! I think you have said, eloquently, what I was thinking. Of course, an open mind means that people need to recognize the good and the bad; nothing is perfect including OS X and the Mac. Having said all that, using XP may be subjecting yourself to unnessissary torture :-)

    Student/Teacher Office for the Mac sells for $135-150, and you don't have to show that you are anything other than willing to pay for it.

    About security. While I completely agree with those who say that we should all get a router, firewall, virus protection, and several spy-ware prevention programs, it just doesn't work for the average person.

    When I help someone with a PC who has a seriously infected machine, I find several things of interest.

    Most have an anti-virus program, but have let their subscription lapse. When I mention this, they get angry about the idea that they should HAVE to pay for a subscription. They feel as though they shouldn't have to pay for something on a yearly basis to use something that they have already bought.


    The idea of getting two or three anti-spy-ware programs is also something that they can't understand, or like. When I explain that even having these programs doesn't mean that they won't still get infected, even though the probability is much less, they are bewildered. They don't WANT to understand that they have to be proactive about these problems.

    They just want to use their machines.

    If you rarely buy anything, go to obscure sites (and with the new fly-by trojans...), not open e-mails, etc., you won't likely get infected. I suspect that those who have all of the protections, and claim to never get infected, don't really do as much as they have us think they do. I don't see Anand web surfing frivolously, downloading questionable files from newsgroups, and subscribing to porno sites etc.

    Most people do at least some of those things.

    No matter how you look at it, OS X is far more secure, for the average person, than XP. If we all played by the rules, and Microsoft did the right thing, it might be different.

    One reason that SP 2 is having as many problems as it has been, is because even though it's got a number of services turned off by default, when you use .net, or need certain services from office etc. they have to be turned on again. OS X doesn't need most of those services to accomplish the same things. FreeBSD is also one of the most secure UNIX variants. Linux, by the way, is turning out to be not that much more secure than XP is, going by all of the successful exploits reported.

    Just wanted to say that - as a long-time Mac user - I really respected this article for its honesty of approach. I was really impressed. While of course I might quibble here and there about some things (Windows security, adware and virus issues were strangely absent;-)) I can genuinely trust the writer's attempts at balance, and I give his opinions the weight they deserve. he's done a fine job.

    At the moment I am travelling in the opposite direction to the author - I've just started using an XP machine for course work - and this article has helped me to see my experience in a more balanced light. Some of the criticisms he has - and my own criticisms when using XP - are based upon long-established working habits and prejudices. The clever trick is to see through those prejudices to look to the root of the system. What is the system trying to achieve? Does it do it better or worse? Honestly?

    OS X is a wonderful system, and I recommend those who haven't looked at it to do so. I'm enjoying the journey of discovery with XP - and trying to keep an open mind when it does something I'm unaccustomed to. However, the best lesson is perspective. If we don't give the other system a proper try, how can we make justified comments upon it. The author of this piece set out to do just that - and the results speak for themselves.

    I suppose my one crucial point is this - if we all keep open minds about the possibilities for innovation from different computer systems, and don't let the zealots on both sides take over the asylum, then we are all winners. Because the market in ideas can function without prejudice, and a good technology implementation can be seen for what it is - rather than through the prism of reality distortion fields or slick marketing.

    In reply to post #167 by Victor, thanks for the commentary.

    Yes, I could have been much more specific. So perhaps I should have reworded my thoughts to read "10 most popular software requests" or some such thing. Also, I was playing "Devil's Advocate" to some degree as I believe a somewhat critical eye represents the best approach when you want to improve something.

    I agree, Mellel is a first rate word processor and an excellent deal. I've been using it since its early days. I think it cost $19.95 when I purchased it. Instead of BBEdit, I use skEdit, which is reasonably capable and has great potential. As for Filemaker Pro, it is an expensive option as is Keynote, given that they represent the equivalent of only a single module each from the Office suite. Mesa 3 from P&L software is a top rate spreadsheet and at $30.00 a great value.

    Hadn't heard of Blogwave Studio. I use the freeware MacJournal, which is an excellent Journal hampered only by its limited functionality. Haven't heard of Quicksilver, and can't use it anyway since I'm waiting for Tiger before upgrading from Jaguar. As for the other suggestions, been there and not terribly impressed generally.

    Any other thoughts on great Mac software deals anyone?

    Re: inexpensive alternative to MS Office

    If you really need ALL the functions of Office, the total cost of the apps listed above would exceed the price of Office 2004 for the Mac (C$560 Std, C$700 Pro). So, at this time there seems to be no inexpensive substitute. One avenue you might try is to enrol in a community college course and use student status to purchase Student/Teacher Edition of Office (about C$225), which would allow you to install on up to 3 machines.

    Chris North wrote in #166: How about the top ten most needed apps on the Mac

    Top ten most needed from what perspective? CAD? Web design? Database development? 3D Rendering? Business intelligence? Customer relationship management? Seismic data interpretation? Medical imaging? Small business collaboration?

    Anyway, some suggestions based on your list:

    Advanced inexpensive OS X native CSS Editor
    StyleMaster, http://www.westciv.com/software/index.html

    Advanced inexpensive OS X Native XML Editor
    Hmm... they all seem to be Java-based, so no go...

    However, for text editing, instead of BBEdit, try
    TextMate, http://macromates.com/

    OS X advanced personal journal with photo and file wells
    BlogWave Studio, http://www.littlehj.com/

    OS X native advanced but inexpensive alternative to Photoshop
    Stone Design Stone Studio, http://www.stone.com/

    OS X native advanced but inexpensive alternate to MS Office
    Word: Mellel, http://www.redlers.com/
    Excel: MarinerCalc, http://www.marinersoftware.com
    PowerPoint: Keynote, http://www.apple.com/keynote
    Access: FileMaker Pro, http://www.filemaker.com

    Oh, and if you're on OS X 10.3, you should try QuickSilver:

    Further to my last post, here's a thought for Anand: If you are looking for a followup article to do on Macs, how about the top ten most needed apps on the Mac? You could take a poll or something then describe where the biggest deficiencies lie and which apps would best fill them. Maybe, you could help convince a few companies like Jasc, or Xara to port their products.

    Here is a quick list to start with:
    Advanced inexpensive OS X native CSS Editor
    Advanced inexpensive OS X Native XML Editor
    OS X advanced personal journal with photo and file wells.
    OS X native advanced but inexpensive alternative to Photoshop
    OS X native advanced but inexpensive alternate to MS Office.

    Please no multi-platform java apps.

    Just a thought...
